APPARATUS roa .ATTACHING arenas TO SOLES IN THE MANUrAcrnnE'or sr-ionsf 1 '0 all whom it may concern:

Be. it known that I, 'fARTHUn BATES, a

subject of the Kingof England, residing at Leicester, Leicestershire', England, have invented certain Improvements inApparatus for Attaching Uppers to Soles in, the Manufacture of Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characterson the drawings indi cating like parts in the several'figures.

This invention relates to animproved apparatus for attaching uppers to soles in the manufacture of shoes. I l

The invention has reference more partic-- soleby metallic fastenings inserted at in tervals through the upper and into the sole. In the useof metallic/fastening machines to attach uppers tosoles, the shoes with a last therein is presented in operative relation to the fasteninginserting mechanism with the upper in engagement with apart of the fastening inserting mechanism ad acent to the passage through which the fastenings are driven. It has been found in the operation of such machlnes that the upper is likely to be so stretched over the sole between the successive fastenings as to cause a gradual accumulation of material of the upper in advance of the inserted fastenings which must be disposed of in a largefold or pucker. There, is a special tendency to the formation of these undesirable folds or ,mechanism and to retain the upper during relative movement of the upper andv sole. As shown, the upper engaging member 1s so formed as to be receive'din a groove in the sole and to operate to press the upper thereinto. M

In the illustrative constructionthere i also provided a support to sustain the shoe inoperative relation to thethroat piece,the

support being constructed and; positioned movement of the shoe while: maintaining the shoe in operative relation to the throat piece;

Thenovel. mechanism is herein shown. as embodiedin a staple fastening machine such as is dis'closedinthe patent to Borden, No; 1,016,930, granted February 13, 19 12. The scope of the invention isnot, however, to be limited thereby. v I 1- Other obi sets and features of the invention will appear as, thefdescription proceeds;

In the drawings,

Fig. 1 is a side stapling machine of the type illustrated in the patent above cited-having a throat piece and worksupportconstructed in accordance with the present: invention and illustrating a clog shoe presented to the machine in; posiation to have its upper secured to its sole,vv w

a clog. mounted on the Work support, in 0peratlve engagement Wltll' the throat piece.

. l The frame of the, stapling machine is des--- ignated 2 and has mountedthereon a fixed,

bracket l seated in a socket 6 formed in a projecting portion. of the frame-and se-k cured in .said socket by a screw 8.., Tl1e bracket 4 has itsend o utturned awayfrom the machine at 10 and has. pivotedthereto' the bell. crank member 12. by the fulcrum stud 14, the bell crank member 12 being se-H cured on the-studby a;set.-;screw 16.. The

short end 18,0fthe bell crank lever is forked and has rotatably 'mounted in bearings formed "in 1 the forked portions thereof; a

rod 20 which receives rotatablyja: pin .22 having areducedportion indicatedat 24 permitting rotation of the pin22relatively to the rod. 20 but, preventing lengthwise movement of the pin relatively to tliGIOd x The pin 22 is threaded at the end toward the frame of the machine and the threaded. por= tion of the pin is received into a cylinder rotatably mounted in the upper end of the bracket 4. The other end of pin 22 is pro-- vided with. a milled head 28, H

The longer arm of the bell crank member 12 is formed with a work supporting surface'upon which is secured by screws 32,.

' drawing a convenient construction of work support for the purposes of the invention. This support forms no part of the present invention but is disclosed and claimed in my fined in the appended claims.

application Serial No. 432,304 renewed December 21', 1920 (originally filed October 4-, 1917, Serial- N0. 1'9at,72l)..1 It is to be under stood that any other suitable construction of work support can be substituted there for within the scope of the invention as de- The work supporting attachment may even be entirely dispensed with and the machine used with the shoe supported only by the hands of the operator.

The throat piece 36 is supported from the head of the machine by the arm 38 in the manner fully illustrated and described in the before-mentioned patent, the. passage of the throat piece which receives the fastening for attaching the upper to the sole being indicated at 10 and said throat piece having its lower end beveled on either side as indicated at 4:2 and 44. The throat piece is reduced in width at its delivery end and carries a bar 16 provided with grooves 418 in each end thereof in. which are mounted I plates 50 and 52 detachably secured to the bar by headed screws 54 and 56 respectively.

The plates 50 and 52 have their lower ends the teeth 58 of the plate 50 at the left of the throat piece. being inclined somewhat to the right and the teeth 60', ofthe plate 52 at the right of the throat piece being inclined somewhat tothe left, the teeth of both plates being, inclined in a direction toward the month of the throat piece 36. It will be noted byreference to Fig. 3 of the drawings that the reduction in width of the throatpiece 36at its lower or delivery end. permits the inner edges of plates 50 and 52 partially to underlie the passage 40 at the lower ends, the inner edges of the plates 50 and 52 thereby forming extensions of the walls of the passage 10 and operating to guide the fastenings below said passage.

In lasting shoes by means of the above-described machine, the operator takes an upper with a last in it and already connected at a few points to the sole edge and thrusts the work upwardly against the throat piece so that the teeth of the plate 50 or 52, depending upon which side of the shoe is being operated upon, will engage the upper near its mar in and push the margin of the upper into t e groove of the sole. Assuming, as indicated in Fig. 3 of the drawing, that the left side of the shoe looking toward the toeis being operated upon, a fastening is first inserted through the upper at a point near the center of the toe portion of the sole, preferably at a distance therefrom equal to one-half of the distance between successive fastenings. Following the insertion of the first fastening, indicated at A, in Fig. 3, the sole and upper are again presented to the throat piece in a position such that the teeth 58 of the plate 50 will engage the margin of the upper and force the same down into the groove of the sole, the upper and sole being engaged by the teeth 58 at a point such that the passage 40. of the throat piece aligns with a point on the sole somewhat further from the fastening previously inserted. than the point atwhich' the next succeeding fastening is to be inserted.

The sole is then moved to the left to bring the point on the sole at which the next suc ceedingfastening is to be inserted into alignment with the passage 40 of the throat piece 36, the points of the teeth 58 digging into the upper and holding it stationary during the movement of the sole. The fastening indicated at B in 3 of the drawings is then driven into place, the relative movement of the sole and upper previously to the insertion of the fastening having caused a little of the fullness of the upper to be taken up between the fastenings A and B. The fastening B having been inserted, the sole and upper are again presented into 0perative relation to the throat pieco, tlie teeth 58 of the plate 50 again engaging the upper in the groove of the sole. The point at which the next succeeding fastening is to be inserted is indicated at in Fig. 3 of the drawings and following the engagement of the upper by the teeth 58, the shoe is again moved to the left whereby the point C of the sole is moved into alignment with the passage l0 of the throat piece and the upper being held against movement by the teeth I pleats.

he operatorhavingcompleted the inserp tion of the fastenings on the left side ofthe shoe, turns the shoe backward, and presents the toe, of the shoe into operative-relation" with the throat piece at, a point cnthe. right side ot the centei: it the toe} In the operation of inserting itastcnings. on the rightl side of the shoe the upper and. sole Willbe presented to the throat piece in a position such that the marginot the upper will be engaged by theteeth .6001? the platef52i ln, starting the operation onthe second side of.
